    keyword=EPR measurement and new wave-plate position

    Performing EPR during run #1620 (two lasers switched off). Also, the beam
    half-wave plate was rotated from -110 to +350 in the control screen prior
    to start of this run. Instantaneous charge asymmetries using the BPMs
    information from the MCC screen seem to be consistent with zero (around
    50+-50 ppm). Using the qasy code, we seem to be in the same ball-park,
    so we keep this wave-plate orientation for now, assuming no drifts.
